Cuttable resin bolts type W
Intended use
-
Cuttable resin bolts type W are intended to use for roof and ribs support in mining roadways. Bolts can be used to protect floor from heaving.
Bolts can be cut by shearer.
Technical description
-
Rods for cuttable resin bolts type W have profiled surface which results in excellent rod-resin binding properties.
- Rods are available up to 12m length.

Installation procedure
- Drill the hole of diameter ø44 ± 0,5 mm and of length equal to bolt length. Reassemble the anchor by placing the washer and shell on the rod.
Place the bolt in the hole and push until the washer touches the rock surface.
Turn the rod and as a result the shell expands in the hole.
Tighten the bolt by applying at least 250 Nm torque in order to obtain the prestress of at least 30kN.
